Bob,

Is a RPM switch something I could find "on the shelf"? or would it be a

custom device.  Do you have any plans?  I like the idea of one with a timer

built in.  I will be running P-mags so I have a tach output.  Please let me

know what is available or if you feel like designing something.  Thanks in

advance.  Don VS

Bob,

I have asked you for assistance regarding where to get a rpm based switch with a timer, as you recomended that I use instead of an airspeed switch.  I noticed that you have not been as active on the list as usual so I am asking if you got my request, and if you have any information  about where to acquire such a switch.  Thanks in advance.  Please do not take this as a complaint, just wondering about the lack of response.  Don VS

Aircraft Extras will sell you an airspeed switch separately from their

Flap protection system if you want:

I bought one for my TCAD  .  .  .

Thanks Tim,

I am looking for a much lower set point.  Bob suggested an RPM switch and I am trying to find out if he knows where to buy the device that he recommended

   Sorry for the delay. I've been tied up with a big

   certification fire-fight. It's really limited the time

   I can spend doing fun things. Should be over this weekend.



   I don't know of any commercial devices. I have a kind of

   generic etched circuit board that carries a little 8-pin

   micro-controller and some general purpose input-output

   pins.



   My program guy could teach a chip to do a tach signal interpretation

   and close a circuit when the signal stays above 1500 rpm

   for 30 seconds. There are probably others on the List who

   could do this too.



   I'm wondering how much interest there would be for such

   a device. It would take quite a bit of high-talent time

   for a one-of-a-kind project.

Bob,
	


Thanks for the response.  I can't venture a guess as to the desire for such a device.  In rv's the only use I can think of is to turn on/off avionics that are normally switched by sqat switches or the like in the certified world.  With the decreased price of tcad units there may be more demand soon??  I am not in a rush, but, I am interested in an electronic version of this switch. Please let me know if you get a chance to look at this a little deeper.  Thanks.  Don VS
